Archaeological Significance
Formation
Evaporite is water-soluble mineral sediment which forms from concentration and crystallization by evaporation from an aqueous solution.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.

All about Evaporite and Flint Properties
Know all about Evaporite and Flint properties here. All properties of rocks are important as they define the type of rock and its application. Evaporite and Flint belong to Sedimentary Rocks.Texture of Evaporite is Earthy whereas that of Flint is Banded, Rough. Evaporite appears Glassy, Vesicular and Foilated and Flint appears Glassy or Pearly. The luster of Evaporite is subvitreous to dull while that of Flint is vitreous. Evaporite is available in green, grey, silver, white colors whereas Flint is available in black, brown, green, grey, red, white colors. The commercial uses of Evaporite are used in the manufacture of ceramic powder, used in the preparation of sulfuric acid and silicon diborite and that of Flint are creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms.
